Product Description

Leading standard organisations and specifiers recognise the importance of removing moisture laden air from building voids, to prevent damage to the building fabric from condensation.

Regardless of underlay used, fibre cement slates require the space between the insulation and underlay to be ventilated. If LR (low resistance) “breather membranes” are used, the space between the underlay and the underside of the slates (batten space) must be ventilated.

The most effective way to achieve this is by having a continuous airgap at eaves and another at the ridge. This allows any moisture to be flushed out of the whole roof slope.

Dry fixed Cembrit continuous ventilated ridges are one piece, lightweight, secure ridge units that are straightforward and time saving for the roofer to install.

Manufactured from the same raw materials and pigments as fibre cement slates, Cembrit continuous vent ridges are available in the commonest roof pitches. They will match the slate colour and roof pitch with no unsightly protrusions or changes of angle, contributing to the sleek effect that can be achieved with Cembrit fibre cement slate roofs.


Fix twice through the wing on both sides. Fixing holes to be 3mm diameter greater than the diameter of the screw fixing’s shank. Pre drill 4 fixing holes in the locations shown on the photo above, recommended fixing 6.3mm x 90mm self-tapping Sela type screw. The open end of the ridge overlays the socket on the previous unit. It is advisable to seal the joint with a bead of mastic in the groove on the socket, particularly in exposed locations.

  • Compatible with all fibre cement slate brands.
  • Lightweight, easy to carry, cut and install.
  • Continuously ventilated so meets British standards, codes of practise, NHBC guidelines.
  • Low profile in various angles for unobtrusive skyline.
  • 8 dry fixings (no mortar required) per linear metre means extra secure ridge.
